It can be very congested leaving MGM after fantasmic. There are hordes of people. Driving may be you best bet, and suggest you head for the boardwalk and enter through the international gateway. The only problem may be the timing of all this. Epcot closes at 9:30 PM during the holidays..not sure if we would be able to get from MGM to Epcot and still have time for a drink! Another suggestion may be to have the Epcot group begin in Mexico, so by the time the others catch up later in the evening you may be somewhere around France or England..which is closer to the inernational gateway. Of course, you could also extend the party ouside of Epcot and begin your journey around the boardwalk, beginning at the ESPN club! Oh, so many choices and so little time!! The problem is, each event sounds like a great time...think cloning will be avaialble by the time the DIS CON rolls around?
